Uploading a file by parsing request

[Fawad Ali]

Hi All,
I have a form where I place <input type="file" /> tags. When the form submits, I want to write the image to a server directory. So I cannot do it in the normal Struts 2.0 way. I have to parse the request and get the files out of it and write it to a server directory. I am using the following code. It works in Servlets but not in a Struts framework.

public class FileUploader {
	private static final String TMP_DIR_PATH = "/images/uploads";
	private File tmpDir;
	private static final String DESTINATION_DIR_PATH ="/media";
	private File destinationDir;
 
	
	public File writeImage(HttpServletRequest request, ServletContext context, String name) throws Exception{
		File file =null;
		String realPath = context.getRealPath(TMP_DIR_PATH);
		tmpDir = new File(realPath);
		if(!tmpDir.isDirectory()) {
			throw new ServletException(TMP_DIR_PATH + " is not a directory");
		}
		realPath = context.getRealPath(DESTINATION_DIR_PATH);
		destinationDir = new File(realPath);
		if(!destinationDir.isDirectory()) {
			throw new ServletException(DESTINATION_DIR_PATH+" is not a directory");
		}
		DiskFileItemFactory  fileItemFactory = new DiskFileItemFactory ();
		//fileItemFactory.setSizeThreshold(1*1024*1024); //1 MB
		fileItemFactory.setRepository(tmpDir);
 		ServletFileUpload uploadHandler = new ServletFileUpload(fileItemFactory);
		try {
			List items = uploadHandler.parseRequest(request);
			Iterator itr = items.iterator();
			while(itr.hasNext()) {
				FileItem item = (FileItem) itr.next();
				/*
				 * Handle Form Fields.
				 */
				if(item.isFormField()) {
					
				} else{
					/*
					 * Write file to the ultimate location.
					 */
					if(name!=null && name.equals(item.getFieldName())){
						file = new File(destinationDir,item.getName());
						item.write(file);
						break;
					}
					
				}
				
			}
		}catch(FileUploadException ex) {
			
		} catch(Exception ex) {
			
		}
		return file;
	}
}

Line 25 of the above code returns either null or empty list. I call it as follows from a Struts action.

FileUploader fileUploader=new FileUploader();
				    try{
				    	fileUploader.writeImage(request, ServletActionContext.getServletContext(),"section_"+section.getEntryFormSectionId());
				    }catch(Exception e){
				    	
				    }

Any ideas on what I may be missing here and if there are any other alternatives, please let me know.

Thanks in advance.
